用內部連接的組合插入

Question

如何創建此選擇語句的插入語句？

SELECT et 
FROM user 
     inner join petrazafa.class_room 
     using(id) 
where title like '%11%' 
    or title like '%12%'; 

我需要插入所有的et = 1;

感謝

Answer 1

編輯1：

我認爲這裏有一個答案：Use select query inside the Insert query for the same table name

對於你：

INSERT INTO `yourtable`(et) 
SELECT et 
FROM user 
     inner join petrazafa.class_room 
     using(id) 
where title like '%11%' 
     or title like '%12%'; 

關注DOC：

INSERT ... SELECT Syntax

文件爲例：

INSERT INTO tbl_temp2 (fld_id) 
SELECT tbl_temp1.fld_order_id 
FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100; 

Answer 2

試着這麼做

INSERT INTO user(1 as et) 
SELECT et 
    FROM user 
     inner join petrazafa.class_room 
     using(id) 
where title like '%11%' 
    or title like '%12%'; 

Answer 3

據我瞭解，你要更新et=1爲title like '%11%' or title like '%12%'

爲

update user u inner join petrazafa.class_room c on u.id=c.id set et=1 where title like '%11%' 
or title like '%12%'
